ALBERT HOLTZ, OF FAIRBURY, NEBRASKA, ASSIGNOR OF ONE-HALF TO ALBERT D.MCCULLOUGH, OF FAIRBURY, NEBRASKA.

TWO-ROW DISK CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 728,798, dated May 19,1903-.

Application filed October 20, 1902. Serial No. 128,019I (No model.)

To all whom it may concern:

Be it known that I, ALBERT HOLTZ, resid-. ing at Fairbury, in the countyof Jefferson and State of Nebraska, have invented certain usefulImprovements in Two-Row Disk Cultivators; and I do hereby declare thatthe following is a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

Thisinvention relates to a new and useful improvement in two-row diskcultivators.

The aim of my invention is to provide a cultivator by means of which tworows may be simultaneously cultivated, and embodies certain'novelfeatures, as will be described more fully hereinafter and finallypointed out in the claim.

In the accompanying drawings I have shown in Figure 1 atop view withportions removed of a cultivator embodying my invention. Fig. 2 shows aside elevation of my two-row disk cultivator with portions re Fig. 3discloses a top view of one of the pivotally-held diskholders. Fig. 4discloses a detail of one of the disk-shaft holders. Fig. 5 shows an endview disclosing the device used in raising and lowering thedisk-holders. Fig. 6 shows a detached enlarged detail of one of thediskholders, showing the connected disk-shaft,

while Fig. 7 shows the arrangement of one of the equalizers used inconnection with my in-.

vention.

In connection with my two-row disk cultivator I employ a straight bar B,preferably of angle-iron, and an adjacent bar 0, preferably ofchannel-iron, as is clearly shown in Fig. 2. These bars form the maintransverse supporting members of the frame used in connection with mytwo-row disk cultivator. Extending from the channel-bar O and beingsuitably secured to the forward frame member B is an ordinary tongue D,as is shown in Fig. 1. Extending from and secured to the horizontalportion of the forward frame member B are the end longitudinally heldand slotted frame members A, and intermediate of these end members A areheld the counterpart slotted frame members A. (Shown in the top view inFig. 1.) These longitudinally held and slotted frame members A and'A aresecured to the-transverse frame members B and O by means of suitablerivets 1, and each of these frame memhers is further provided with theslots a. (Shown in Fig. l.)

Uniting each end frame member A and the adjacent frame memberA upon theopposite ends is an arched bar H, and these two arched bars 11, one ofwhich is shown in detail in Fig. 5, are again united by means of theangleiron intermediate frame member B, (shown in Figs. 1 and 5,) theseframe members H and B being secured by suitable rivets 1.

Extending upward and rearward from the intermediate frame member B is aseat-bar 30, provided with the seat 31, as is shown in Fig. 1. In Fig. 2this seat and its connected bar are eliminated.

The frame members A and A are preferably made of angle-iron and areprovided with the bolts I), used in sets of twos, each set of bolts 13supportingasuitable bearing 2, as is shown in Fig. 4, so that thesebearings 2 may be shifted backward or forward by means of the set-boltsb. Held within each set of bearings 2 is a shaft 2',and revolubly heldupon these shafts 2 and laterally sliding upon the same are thedisk-holding sleeves F, to which are secured the disks E in sets oftwos. These disks face one another, as is disclosed in. Fig. 1.Loosely'surrounding these diskholding sleeves F is a pivotally-helddiskholder comprising the bearing 4, the forwardextending ear 3, and thetrailing arms. 5, as is shown in FigsJl, 2, and 6. These diskholders arepreferably made of sheet'metal, and the trailing arms 5 are bent atright angles to the bearing portion 4, as will be understood inreferring to Fig. 6, and these bearing-arms are provided with theperforations 2'', adapted These sleeves F revolve freely upon the shafts2, held within the hearings or holders 2,while loosely working upon thesleeve F again between each set of disks is a pivotally-held disk-holderprovided with two outwardlyspreading trailing arms, as shown.

Secured to the forward frame member B are two pins 9, each pinadjustably holding a set of equalizer-bars 10, as shown in Fig. 7,provided with suitable perforations, so that the same may be adjustablysecured to the pins 9, and secured to each set of equalizerbars 10 is achain 7, united, by means of the rings 6 and 8,to the disk-holders andthe equalizer-bars 10, as is shown in Fig. l. The remaining end of eachequalizer-bar '10 is provided with a sheave 12, over which extends achain N, secured to the eyebolts 13 of the singletrees 14. (Shown inFig. 1.)

Secured to the trailing arms 5 are the forward bearings 40, receivingthe stems 41 of the cutter-disks 42, these cutter-disks being used insets of twos, and near the end each trailing arm 5 is further providedwith abearing 43, adapted to receive the stem 450E a suitable shovel 46.In this it will be noticed that the main frame of my cultivator issupported by means of the usual wheel-disks E and that I .provide twopivotally-held diskholders, each being provided with two cutterdisks andtwo trailing shovels.

In order to raise and lower the cutter-disks and cultivator-shovels ingoing and coming to and from the field, I provide the standards N,supporting the rock-shafts 32, each provided at one end with anenlargement 30 to prevent the lateral displacement of this shaft, whileat the opposite end each rock-shaft 32 is provided with an ordinarylever 33, provided with a thumb-latch 6, working in conjunction with anordinary notched sector, as is shown in Fig. 5 and as is usual in theconstruction of agricultural implements. These 7 notched sectors aresecured by means of the plates 37, forming a part of the notchedsectors, which plates by means of the bolts 38 are secured to theintermediate frame member B. It will be noticed that these levers 33,secured to the rock-shafts 32, are placed to the right and left andadjacent the operators seat 31. Extending from each rock-shaft 32, asshown in Fig. 5, is a chain 6, and these chains 6' are secured to therings 3', as shown in Fig. 3, secured to the transverse bars 5, forminga part of each pivotally-held disk-holder, as shown.

Now, having thus described my said invention, what I claim as new, anddesire to secure by United States Letters Patent, is

In a two-row disk cultivator the combination with a rectangularsupporting-frame, of a set of arched bars secured upon opposite and rearends of the frame, of two equalizerbars pivotally and adjustably securedto the forward end of said supporting frame, a sheave Within eachequalizer-bar, a chain passing over each sheave and provided at each endwith a singletree, a chain extending rearward from each equalizer-bar,bearings adj ustably secured in sets of twos upon opposite sides toaforesaid supporting-frame, a shaft held by each set of bearings, asleeve revolubly held upon each shaft, supporting wheeLdisks secured toeach sleeve, a pivotally-held disk-holder secured to each sleeveadjacent said supporting disk-wheels, the forward end of eachpivotally-held disk-holder being secured to the aforesaid chainextending from each equalizer-bar, cutter-disks secured in sets of twosto each of said diskholders, cultivator-shovels secured to each ofaforesaid disk-holders, and rock-shafts secured to said disk-holder asand for the purpose set forth. v

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT HOLTZ.
